Description
【考案の詳細な説明】
本考案はドアを閉じた際においてデッドボルトが自動的
に突出してドアが必ずロックされるようにしたドア用ロ
ック機構に関するものである。[Detailed Description of the Invention] The present invention relates to a locking mechanism for a door in which a deadbolt automatically protrudes when the door is closed, thereby ensuring that the door is locked.
以下本考案の一実施例について図面と共に説明すれば、
枠体１に対してテ゛ツドボルト２が摺動自在に支持され
、その内部には牽引部材３が直列的に設けられている。An embodiment of the present invention will be described below with reference to the drawings.
A tied bolt 2 is slidably supported on a frame 1, and a traction member 3 is provided in series therein.
デッドボルト２と枠体１間にはコイルバネ４が設けられ
、デッドボルト２の後端の係合部２ａと牽引部材３の前
端の係合部３ａとが相対向している。A coil spring 4 is provided between the deadbolt 2 and the frame 1, and an engaging portion 2a at the rear end of the deadbolt 2 and an engaging portion 3a at the front end of the traction member 3 are opposed to each other.
５は軸６により回動される駆動子であり、室内側からの
ノブの操作により回動される。Reference numeral 5 denotes a driver that is rotated by a shaft 6, and is rotated by operating a knob from the indoor side.
駆動子５の一側の駆動部５ａは牽引部材３の被駆動部３
ｂに係合し、他側にはデッドボルト２内端の受部２ｂに
対する支持部５ｂが設けられている。The driving part 5a on one side of the driving element 5 is the driven part 3 of the traction member 3.
b, and a support portion 5b for the receiving portion 2b at the inner end of the deadbolt 2 is provided on the other side.
７は閉扉感知フィンガであり、その中間部の長孔７ａを
もって軸８により支持され、常時はその外端７ｂが外部
に突出し、且つ内端７Ｃがデッドボルト２に圧接するよ
うに付勢されている。Reference numeral 7 designates a closed door sensing finger, which is supported by a shaft 8 with a long hole 7a in its middle portion, and is normally biased so that its outer end 7b protrudes outside and its inner end 7C comes into pressure contact with the deadbolt 2. There is.
上記構成において、第１図の開扉時においては、デッド
ボルト２は駆動子５乃至牽引部材３により後退されられ
た状態を閉扉感知フィンガ７の内端７Ｃが係子凹部２Ｃ
に係合した状態において保持されている。In the above configuration, when the door is opened as shown in FIG.
is held in the engaged state.
この状態において閉扉すると感知フィンガ７の外端７ｂ
が対向する固定部材に衝合して揺動しつつ長孔７ａを介
して内部に後退し、この際に内端７Ｃが係止凹部２Ｃを
外れてコイルバネ４により突出する。When the door is closed in this state, the outer end 7b of the sensing finger 7
The inner end 7C comes out of the locking recess 2C and is projected by the coil spring 4.
本考案は上記した如くに成るものであるから、閉扉時に
おいてテ゛ツドボルトを対向する受金に進出させて自動
的にロックすることか゛出来るもので゛あると共に必要
時においてはノブ等の操作により開扉できるものであり
、施錠時においてはデッドボルトの後退を阻止して破錠
が防止され、非常扉等のロックとして好適である。Since the present invention is constructed as described above, it is possible to automatically lock the door by advancing the bolt into the opposite receiver when the door is closed, and when necessary, the door can be opened by operating a knob, etc. When the lock is locked, the deadbolt is prevented from retreating and the lock is prevented from being broken, making it suitable for use as a lock for emergency doors, etc.
